sro? Foa WINDOW sass.

vApplication led September 1,1922. Bei-iai No. 585,803.

Be it known that I, Sinnen T. Cox, a citizen of the United States, residi at Omaha, in the county ef Douglas Vand tate of Nebraska., have invented certain new and useful Improvements in Stops for Window Sash, of which the following is a specification.

This .invention relates to means for supportin window sash in window frames at desi heights, and has for its object to provide a construction consisting of few and simple parts, vso that manufacture will be convenient and economical, and will operate to prevent vibration of the sash; also by means of which window weights, ropes and pulleys and boxes for containing the weights may be avoided.

With the foregoingk objects in viewandA others to be mentioned hereinafter, the invention presents a novel construe-tion, coinbination and arrangement of parts, as described herein and claimed, and as illustrated in the accompanying drawing, wherein,-

Fig. 1 is a view of a window frame in vertical section, to show the usual channels for receiving an upper and a lower sash. Fig. 2 is an end view of a art of a window sash, showing the stile provided with an apertured adjusting-strip. Fig. 3 is a tranverse section on line 3-3 of Fig. 2. Fig. 4 is a broken away side view, partly in section, showing a window sash supported, by the ball of a plunger. Fig. 5 is a face view of a spring ball-retainer. Fig. 6 is an enlarged detail relating to Fig. 4f, showing a casing for containing a plunger and spring. Fig. 7 is a side View of the casing, also showing the ball and ball-retainer.

Referring now to the drawing fora more particular description, the invention is shown and described in connection with av window frame 8 of usual construction, the groove for receiving an upper window sash'" being indicated at 9, and the groove for the lower window sash being indicated at 10,

the parting-strip between the channels beingindicated at 11.

In order that the window sash may be supported at different heights in the grooves mentioned, each stile 12- of a sash is provided on its outer side with a metallic strip- 13, suitable grooves 14 (Fig. 3) being formed in the stiles for receiving the strips, the latter being secured therein by keepers 15, as shown in Figs. 2 and 4, and provided at intervals with apertures 16; and it will be understood that .when a window sash is disposed in its groove it may have sliding movements upwardly or downwardly therein, and that while so disposed the apertured, metallic strips 13 will not be visible.

For the purpose of supporting a sash in a stationar7 position after it has been moved, window-stops 17 are rovided, each consisting of a cylindrical casing 18 containing a spring 19, and a plunger 2O encircled by the spring and having a concavo-convex cap or socket 21 for a mounting therein of a ball 22, the proportion of parts being such that approximately one-half of the ball will project outwardly of the socket, outwardly of the end of the casing.

It will be understood that the spring 19 operates to press the plunger outwardly of the casing to cause the ball to constantly engage the strip and to enter a recess or aperture 16. The strips 13 preferably have plungers inwardly of the casings, against the force of the springs 19, and in the use of the device, only a slight force is required for operation.

'While only a part of a window frame and only two stops 17 have been shown, it will be understood, of course, that four of these `stops are to be employed and used in pairs for one window-frame, one pair beingmounted in channels 9 for controlling an upper sash, and a pair mounted in channels 10 for the control of a lower sash.

In mounting a window stop 17, an operator, after boring a hole in fthe window frame, places the casing and its contents in the hole, the casing preferably being provided with a terminal flange 23 for engaging the frame, as shown in Fig. 4; a spring ballretainer 24 is then placed to partly cover the ball and is secured at 0r near one of its ends to the frame by a keeper 25. This member 24 is entirely detached from other parts of the window sto and consists of a metallic plate or strip ol) sufficient length to operate as a spring and having an aperture 26 of suflcient diameter to partly cover the ball, and it operates to revent the ball from moving outwardly rom its socket under force of the spring 19 when the sash has a movement to cause the ball to enter an aperture of a trip.

It will be seen that, by use of the invention, Window sash may be readily removed from a window frame whenever required; also, since Window-weights are not employed, no cords or pulleys will be used, or boxes for containing the window weights. In operation, when a sash is moved, the balls will roll in their sockets and will roll on the Strips 13; and if the sash. is moved a considerable distance the balls may enter several of the apertures 16, the constant engagement of the balls with the strips, by action of the springs 19, preventing any objectionable rattling noise which otherwise might be caused by vibration.

While l have described construction in detail, I do not wish to be understood as limiting m self in this respect, and changes in size, orm, proportion and minor details may be made as found to be of advantage, said changes being within the scope ofthe invention as claimed.

I claim as my invention,-

In a stop for a window frame and a. slidingly mounted Window sash, an apertured strip on the stile of the sash, a plunger on the frame and provided with a socket, a ball in the socket, means on the plunger for moving the ball and socket outwardly of the frame toward said apertured strip, and an elongated, resilient plate havingl an aperture for receiving a part of the ball, said plate having one of its ends attached and having its opposite end detached from the frame for limiting the movement of the ball and socket outwardly of said frame.

ln testimony whereof, have aflixed my signature in presence of two witnesses.
